Oxidation colorants which contain at least one secondary intermediate and at least one derivative of 5,6-dihydroxyindoline corresponding to formula (I): ##STR1## in which--independently of one another--R.sup.1 is hydrogen, a C.sub.1-4 alkyl group or a C.sub.1-4 hydroxyalkyl group,

Colorants for keratin fibers comprising a 5,6-dihydroxyindoline

Hair dye preparation

This invention relates to a hair dye preparation. More specifically, this invention relates to a preparation for the simultaneous coloring, washing, and conditioning of human hair which consisting essentially of a mixture of:

Preparation for the simultaneous coloring, washing, and conditioning of

This invention is directed to an aerosol container system with two separate chambers, each of which contains a component to be mixed with the other component just prior to use. The container system comprises:

Dual chamber aerosol container

Emulsion-form hydrogen peroxide compositions in the form of an oil-in-water emulsion containing oil or fatty components, emulsifiers and hydrogen peroxide and, in addition, a thickening agent comprising a carboxyl-group containing polymer or copolymer soluble in aqueous alkali in a quantity of from about 1 to about 5% by weight solids, based on the weight of the composition. These compositions are particularly suitable as an oxidizing component in processes for the dyeing or lightening of hair resulting in improved depth of color and brightness.

Emulsion-form hydrogen peroxide preparations for the bleaching and

This invention is directed to oxidation hair dye compositions and their use in the dyeing of human hair. The compositions consist essentially of precursors comprising 2,3-diamino-6-methoxy-pyridines and aromatic amines or diamines. The combination of oxidation dye precursors according to the invention gives bright, deep blue dye finishes having high stability to heat and light.

Oxidation hair dyes comprising diamino-substituted pyridines and

Stabilized liquid preparations for oxidation hair dyes are provided. The oxidation hair dyes comprise oxidation hair dye precursors and an aqueous or aqueous-alcoholic carrier, containing (A) from 5 to 20% by weight of fatty acid water-soluble soap and (B) from 0.5 to 10% by weight of a water-soluble cationic polymer. The oxidation hair dyes (containing a soap and cationic polymer which tend towards inhomogeneity) are stabilized by the addition of from 5 to 30% by weight of a compound selected from the group consisting of: (C) aliphatic or alicyclic C.sub.9 -C.sub.44 dicarboxylic acid water-soluble salts; and (D) amines corresponding to the following general formula ##STR1## .
